Underworld Dreams Combo is an archetype I haven’t played much myself, but one I believe to be a bit underplayed and underdeveloped. It’s not without its flaws, though. One is a weakness to opposing Lightning Bolts and Chain Lightnings, as you give your opponent cards through Howling Mines and want to strand a bunch of those cards long enough so your Winds of Change can combo with Underworld Dreams to finish the opponent off. Against a player with 8 bolts, that can just mean a swift loss for you. How can we solve this?
One idea I got was to add Dark Heart of the Wood to the deck. It makes perfect sense in theory: green also adds Sylvan Library and Fastbond, which combo with Howling Mine and Winds of Change, as well as Avoid Fate to protect your heavy permanent-based game plan. I arrived at this list:
Then I sleeved it up and did some battle. Only online against one deck, but out of 5 or 6 games, I won exactly 1, and was never close to winning any other. This deck sucks. And now I’m going to tell you why.
First, there’s the small issue that you want all your lands to be forests producing black mana. Yet you can only run so many Bayous. This leads into the second point: using Dark Rituals to solve the black mana deficiency and power out the Underworld Dreams: that turns your three-card combo (Dreams, Howling, Winds of Change) into a four-card one, and that’s very much harder to assemble.
And the combo is already not the smoothest. It seems like Howlings and Winds should help you find what you need, and that is partly true, but when you finally get and resolve an Underworld Dreams, you have to start comboing for real, surviving several turns while doing so. The deck can be great when you get turn 1 Dreams or draw a bunch of restricted cards, but that’s it. This is very different from the Power Monolith builds where you actually win when you get the combo, and one reason I chose to include a single copy of Lich in there. (No, not really. I included the Lich because it’s sweet. Who am I kidding?) Dreams Combo is a whole other story. It’s about chip damage, which makes me lean towards playing Lightning Bolts. Still I’m not a believer in Black Vise, but we’ll see. I have several versions of this archetype on my bucket list so I’ll make sure to revisit it in the future.
(In fact, I’m having a hard time to decide whether the great divide between different kinds of combo decks is between having and not having Howling Mines or caring or not caring about chip damage. Howling builds have to worry about giving the opponent cards while setting up, but maybe that’s not so different from the draw-7s. I used to think this was a useful differentiation, but now I’m leaning towards chip damage being more important for playstyle and deck building. The problem, then, is that it’s almost only Dreams combo which cards about chip damage, with the possible exception of some Mishra’s Factory-using Candleflare lists. Well, we’ll see, once I get to the Combo School of Magic theory article series. One of these days. :) )
So what lessens can we learn here?
First: when your mana base is actively fighting against you, you might be doing something wrong. It can still be worth it; you have to play a lot of forests for Dark Heart of the Wood in Mirrorball, or a lot of red mana in any Fork deck, or all blue-producing lands and still not having enough blue mana in Twiddlevault or Power Monolith, or just being generally miserable when trying to cram factories or the wrong kind of basics (like plains in Power Monolith or island in Mirrorball). But that is exactly it: the price has to be worth it.
Second: you want to minimize the number of dead or weak cards in your deck. An Underworld Dreams you can’t cast is a dead card. In a similar vein, Winds of Change with 2 or 3 cards in hand is just not a powerful card.
Third: combo decks work on ignoring what the opponent does, by and large. When you win gradually, and depend on the opponent having cards in hand most of the time, you very much can’t ignore that.
And that is in addition to the usual problems of combo decks, like dying to Blood Moon, Energy Flux, Nevinyrral’s Disk, and Underworld Dreams. Some of those can be mitigated in different ways, of course, but their presence has to be considered. And if you die to all of them, you have to do something really powerful in order for it to be worth it. Handling Energy Flux by going for a 3rd turn powerball kill is certainly a plan, for example.
All of these problems can be handled in different ways. But this list is not the one to do it with.
